The name Phoenix remained until April 14, 2003, when it was changed because of a trademark dispute with the BIOS manufacturer Phoenix Technologies (which produces a BIOS-based browser called Phoenix FirstWare Connect). The name Mozilla was revived as the 1998 open sourcing spinoff organization from Netscape. The name for this would-be 'Mosaic killer' was meant to evoke the building-crushing Godzilla. The name Mozilla began as the internal codename for the original 1994 Netscape Navigator browser aiming to displace NCSA Mosaic as the world's most popular web browser. This name carried the implication of the mythical firebird that rose triumphantly from the ashes of its dead predecessor, in this case Netscape Navigator which lost the 'First browser war' to Microsoft's Internet Explorer. After it was sufficiently developed, binaries for public testing appeared in September 2002 under the name Phoenix. The project that became Firefox began as an experimental branch of the Mozilla Suite called m/b (or mozilla/browser).
